Triple Infrared Detectors

FlameSpec-IR3 is the next generation of Triple IR Flame Detector, it is being introduced to further enhance the protection and safety for those high risk and high value industries.​

The FlameSpec-IR3 will detect fires and explosions extremely fast, thus allowing preventative action to be initiated even more rapidly and minimizing the consequences!​ It provides ultra-fast response, high performance and reliable detection of all types of hydrocarbon fires (visible and non-visible). The detector addresses slow growing fires as well as fast eruption of fire using improved Triple IR (IR3) technology. It operates in all weather and light conditions with highest immunity to false alarms. The unmatched detection times and distances are: 

• Detection within 40 milliseconds of fireballs or explosions 
• 1.2 seconds – for 1 square foot n-heptane pan fire at up to 15m
• <4.1 seconds– for 1 square foot n-heptane pan fire at up to 70m 

Add to that, the integral event recording, on top of the proven superior capabilities of Triple IR (IR3) flame detection and you have a very powerful safety tool to protect your personnel, plant and process.

FlameSpec-IR3–HD has the addition of Integral HD quality video, with event recording, on top of the proven, superior capabilities of Triple IR (IR3) flame detection, providing a very powerful safety tool to protect personnel, plants, and processes. The detectors high-definition (HD) video output of the monitored area provides clear imaging of a fire event and of personnel at distances up to 30m. This allows the rescue team to be aware of the exact situation before entering the hazardous area. The detector automatically records video of any fire event (1 minute pre- and up to 3 minutes post alarm initiation). These features, along with the built-in event logger, provide additional means to study the cause and development of fire events for “lessons learned” reviews. 

Key Benefits

FlameSpec-IR3 and IR3-HD:

• Extreme sensitivity - up to 80m for a 0.1m² n-heptane pan fire.  
• Ultra-fast detection mode - detection within 40 milliseconds for fireballs or explosions.  
• 1.3 second detection time - for 0.1m² n-heptane pan fire at up to 15m distance.  
• Data/Event logger - alarms, faults and other relevant events are logged to non-volatile memory.  
• Built-in-Test (BIT) - Automatic and manual self-test of window cleanliness and the overall operation of the detector.  
• Window heater to avoid condensation and icing.  
• Tilt mounting bracket can be connected either above or below the detector.  
• High immunity to false alarm.

FlameSpec-IR3–HD only:

• HD video output with Automatic HD video recording of fire events. Visualization of hydrogen flames that are invisible to the human eye.  
• Ethernet communication – in addition to the standard methods, such as Relays, 4-20mA and Modbus.
